This 2017 all-wheel-drive Audi A6 C7 has a 3.0-litre V6 twin-turbo diesel engine and an EDC17CP44 ECU. Before tuning, the dyno showed 308 hp and 637 Nm. The video compares these figures with stated factory ratings of 326 hp and 650 Nm.

Engine and gearbox software

The workshop carried out a Stage 1 engine calibration and adjusted the automatic gearbox software. The car was then road-tested. The technician says the DPF, catalytic converter and AdBlue system remained installed; no visible smoke was observed during the drive.

Figures stated in the video

The title lists 345 hp and 743 Nm, while the spoken narration gives 355 hp and 745 Nm. The exact final measurement should be confirmed against the dyno printout.
